摘　　要：确定了一种2-DOF铰接轮式越野挖掘机行走系统中发动机-泵功率匹配区域和实现原理,并分析了变量泵-变量马达系统工作参数。研究了影响车辆爬坡能力的因素,合理设计了最大牵引力和分动箱传动比。在此基础上设计出该挖掘机在不同工作模式下的牵引特性,为该车行走系统的设计和分析提供了依据。The engine-pump power matching area and realization method of the driving system of a 2-DOF wheeled off-road excavator were determined, and operation parameters of the variable displacement pump and variable displacement motor system were analyzed. Moreover, the factors affecting the grade ability of the excavator were studied, and the maximum traction force and the gear ratio of the transfer case were designed. And then, the traction performance of the wheeled off-road excavator in various operation modes was designed. The study provided basis for the design and analysis of the excavator driving system.
